1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Introduction: Coal Fly Ash (FA) poses a significant environmental challenge due to its physicochemical properties and its enrichment in potentially toxic elements (PTEs). Phytoextraction can be a cost-effective and eco-friendly approach to remediating sites contaminated with FA and PTEs. However, the role of soil amendments, such as biochar, in phytoextraction of PTEs from FA-contaminated soils remains underexplored. Methods: This study investigated the effects of biochar on plant biomass production and patterns of PTE accumulation in FA-amended soils using a controlled greenhouse experiment. Four plant species-switchgrass, tall fescue, hairy vetch, and sericea lespedeza-were grown in varying proportions of soil, FA, and biochar. Shoot elemental concentrations were quantified for 20 PTEs using ICP-AES and analyzed using correlation-based and multivariate analyses. Results and discussion: The results showed that FA amendment significantly reduced the plant shoot and root biomasses, while biochar enhanced the biomass accumulation of plants. Analysis of PTE bioaccumulation behavior of plant species revealed that Ca-Mg had a strong negative correlation with Ba-Sr uptake and very weak relationship with Al-Si. A weaker relationship between the bioaccumulation behavior of Al-Si and Fe-S was recorded in this study. Legumes (hairy vetch and sericea lespedeza) clustered towards Ca-Mg, while grasses (tall fescue and switchgrass) showed clustering towards Al-Si.
